Portable clip-on light. Ideal for reading or seeing in hard-to-see spots, easily attaches to where you need warm white light. The warm white LED (light emitting diode) light provides a more natural reading experience with the excellent contrast you need to read. The scientifically designed beam is engineered to provide wide illumination and reaches up to 4 meters - far enough to double as a personal flashlight. A flexible neck allows you to precisely direct the light for reading or use it as a compact LED flashlight for household and automotive tasks. This little reading flashlight is impact-resistant up to 1 meter for durable use. Includes (2) CR2032 lithium batteries to provide a run time of 25 hours for long-lasting light. When not in use, this slim LED book light collapses and locks for easy storage.
